According to the disclosed embodiments, system 300 includes that the number of HVAC controller 324 is connected to via communication network 336
According to processing system 340.According to some the disclosed embodiments, data processing system 340 is located at geographically-distant HVAC unit
At 308 position.Communication network 336 can be internet or the communication network of any other type.Data processing system 340 is wrapped
Processor 344 is included, the processor may include for carrying out analyzing processing to the various data received from HVAC controller 324
Program code.Data processing system 340 may include the interrogator for being configured to be periodically polled HVAC controller 324
352.In response, HVAC controller 324 periodically transmits recorded data via network 336 to interrogator 352.Data
Processing system 340 includes being configured to store the database 348 of temperature data.Processor 344 can access database 348 to examine
The rope data stored with analysis.Processor 344 may include program code, for analyzing stored data with determination
Whether HVAC unit operational failure and can be transferred to one or more of HVAC controller 324 for generating by network 336
A control signal 356.As previously discussed, control signal 356 can make HVAC controller 324 disable HVAC unit 308.Root
According to some the disclosed embodiments, in response to controlling signal 356, HVAC controller 324 can transmit disabling letter to thermostat 320
Number, to make thermostat 320 disable HVAC unit 308.
According to the disclosed embodiments, processor 344 may include condition and the response for being configured to analysis wide scope
The program code of one or more control signals is generated in condition.For example, it is contemplated that wherein thermostat set point is 75 degree, region
Temperature is 75 degree but is supplied with the scene that air themperature is 85 degree.Point based on the data recorded on the period of pre-determining
Analysis, processor 344 can determine 308 operational failure of HVAC unit, but other HVAC units in building may be just cold
But space.Therefore, processor 344 can generate control signal so that HVAC controller 324 disables HVAC unit 308 for repairing
And message is sent to which notice has disabled the unit of operational failure.
For example, it is contemplated that wherein thermostat set point is 75 degree, external temperature is 90 degree, but it is 90 degree to be supplied with air themperature
Another scene.Based on the analysis of the data recorded on the period of pre-determining, processor 344 can determine that HVAC 308 is transported
Turn failure and is likely to blow extraneous air.Therefore, HVAC unit 308 can be disabled for reparation.
For example, it is contemplated that wherein thermostat set point is 66 degree, external temperature is 85 degree but is supplied with air themperature to be 100 degree
Another scene.Based on the analysis of the data recorded on the period of pre-determining, processor 344 can determine HVAC unit
308 are heating building 304 rather than cooling, therefore are had adverse effect to regional temperature.Therefore, processor 344 can be with
Control signal is sent so that HVAC unit 308 is disabled to HVAC controller 324.
For example, it is contemplated that wherein oven heated/cooling setpoint point is 64/73 degree, regional temperature is 75 degree and supplies sky
Another scene that temperature degree is 85 degree.The analysis of data on the period of pre-determining can indicate that HVAC unit 308 is not good
Good berth, but the fan most of the time drying.Therefore, HVAC unit 308 can be disabled by processor 344 for repairing.
For example, it is contemplated that wherein HVAC unit 308 has another scene of 67 heating setpoint point and 76 cooling setpoint point.
External air temperature is 25 degree, therefore HVAC unit should heat the space in building 304.Regional temperature be 55 degree simultaneously
And supply air themperature is 30 degree.The analysis of data on the period of pre-determining can indicate that HVAC unit 308 is likely to just
It is blown in building 304 by cold extraneous air.Therefore, HVAC unit 308 can it is disabled until its can be repaired for
Only.
According to some the disclosed embodiments, processor may include the program code for executing following procedure：
（1）If thermostat is set for cooling down, but is supplied with the amount that air themperature is more than regional temperature pre-determining, then
HVAC unit will be off.
（2）If thermostat is set for heating, but is supplied with the amount that air themperature is less than regional temperature pre-determining, then
HVAC unit will be off.
（3）In determining whether that HVAC unit should be turned off, regional temperature can be considered as factor, but not exclusiveness
Factor.For example, even if regional temperature in specification, if the processor determine that other HVAC at the place may compensate fortune
Turn the HVAC unit of failure, then HVAC unit can be turned off.
（4）Indoor and outdoors humidity data can be considered in processor, if available.If HVAC unit is being owed
It executes but still dehumidifies to space goodly, then HVAC 308 can not be turned off.
（5）Processor can prevent all HVAC units to be turned off, because they can provide air circulation.
（6）HVAC unit can not be turned off, if the place accordingly instruction.For example, the place can indicate
HVAC unit supplies air to computer floor or data center, and therefore HVAC unit can be considered as automatically controlling and
Speech has been too important and therefore can not be turned off.
（7）If the CO2 levels in space are more than maximum permissible level, HVAC unit will not be turned off.
Fig. 4 depicts the flow chart of the process for monitoring and controlling HVAC unit according to the disclosed embodiments.It should
Process for example can be configured to execute one or more data processing systems of action discussed below（Such as count
According to processing system 200）Middle execution, one or more of data processing systems are known as " system " with odd number.Process can pass through
Be stored in it is in non-transitory computer-readable medium, so that one or more data processing systems is executed holding for such process
Row instructs to realize.For example, HVAC using 228 may include executable instruction so that one or more data processing systems execute
Such process.
Process starts from block 404, wherein system receive the supply air themperature to being coupled in the pipeline of HVAC unit into
The supplying temperature data of row instruction.System can be in response to being controlled by the poll of interrogator associated with system by from HVAC
Device receives supplying temperature data.Supplying temperature data can be transmitted by the communication network of such as internet etc.
In block 408, system receives the regional temperature data in the space that HVAC unit is serviced.Regional temperature data can be with
Such as the temperature in the space of instruction interior of building.Regional temperature data can be by being located in the sensor sense of interior of building
It surveys.
